AC hoses

[Yuran]

Has anyone found replacement A/C hoses from the aftermarket to replace 1993 1st gen. trucks? My napa store has no listing available and the local hose shop didn't want to tackle it. any help is greatly appreciated.

I have been looking also. I believe the 89-91.5 hoses are available but I have not seen hoses for the 91.5-93 trucks. I think that you have to be careful because some places list the old style hoses to cover from 89-93.

I just went threw this on my truck. The condenser side hose the metal ends were about rusted off. I found a bad hose with good metal ends. Here are some pic's and part numbers.

This first pic shows the old hose with the spring lock connection removed.

This pic shows the new spring lock with a section of hose attached. That hose is long till fitting in the truck. The smaller hose has a compression fitting to #6 barrier hose for 134. That hose is long also. The other end of the hose is shown with its compression fitting for the dry end.

This pic shows the compressor end of the large hose. That hose is a #8 hose. Both are bigger than the factory hoses were. But I couldn't the fittings I needed for the smaller hoses.

Here is a pic of the finished condenser side of the hoses.

Here is the compressor side finished.

Here is the dryer side. Now during mock up I didn't like the looks of that straight fitting. You can't get it with a 45 degree bend. I tried.

Parts used.

Small compression fitting at the condenser. NAPA 401050

Larger compression at the dryer. NAPA 401067

90 degree fitting at the compressor. NAPA 406902

spring lock connection. NAPA 405472

134 conversion adapters for the R12 fittings. 409902 and 409903

Any parts store should be able to cross these numbers out. They are dorman numbers.


I have not done the larger hoses yet. I needed the A/C up and running for MM event in a few weeks. 134 is cheap. I'll just drain it later and do the large hoses.


BTW those compression fitting used are the same type used on hyd steel tubing. These are rated a lot higher PSI than a A/C system will ever see.

Any Radaitor shop that doies after market installs can make up AC lines , even custom ones , if you cant find one call Mac Radaitor in Portland , Oregon

Very nicely done! Impressed! Was just playing with AC hoses this weekend. I may have to ponder this direction as well.

And no. The 90 and down hoses have been discontinued.

Robert the IC truck hoses are N/A also. I did check.

I have found a bigger condenser that might work in a 1st gen. I'll post about that when I get one rounded up.

I'll do the bigger hoses at the same time.

 

[RSchwarzli]

Well that sucks.

Yes....condenser. I am now running a gen 2 condenser in the 1990. AC is real cold.

 

[DVolk]

How did the gen 2 condensor fit ?

 

[RSchwarzli]

Good. It only took maybe 20 of the 500 hours to fit.

 

[Philip]

The one I have measured out might be close to a drop in. I won't know till I find a used one and get the grille out. The lower valence center mount might cause a problem.

Yes. I cut my center valence out.....that is now MIA minus 16" on either side. LOL

joy , nothing like hacking and cutting , has any one ever tried a universal style

 

[RSchwarzli]

Universal mounts are for wimps! :-laf

 

[RWherley]

That's right its only cool if its custom

The problem I see with universal types. You have no idea of what quality controls are used during the build process. Do they use the cheapest thinnest materials they can. Do they just say looks good and throw it in a box.

A OEM part is made to the OEM spec's. The OEM tells a company what the quality standards are. If the company doesn't follow those rules. Many parts will get shipped back. I would rather find a close fit from a factory made vehicle. I thinks its better than using a unknown part from a unknown company.

 

[DVolk]

I agree on that part im not oposed to useing anouther brands parts as well either
